If you've ever wondered if there's a science behind what makes a scary movie scary, then we have good news for you. A UK study from Broadband Choices applies a scientific approach to ranking the scariest movies of all time. This in-depth study tracked the heart rates of 50 participants viewing over 120 hours of horror films in immersive 5.1 surround sound. The study showed that while a resting heart rate is 65 bpm, the scariest film caused an average heart rate of 86 bpm and a spike of 131 bpm.

The results of the study were surprising in some cases. Horror films ranging from gore fests to psychological thrillers were deemed to equally get hearts racing, while favorites like Friday the 13th and The Grudge didn't even crack the study's top 20 scariest films.

Below, we'll show you which films are scientifically shown to get your heart pumping, and you can decide which ones scared you the most.
